- All 4 lakes around Chennai have dried up, say local authorities
- Chennai requires 830 million litres of water a day
- In many areas, piped water being supplied only once in 3 days
There is no daily supply of drinking water in Chennai as the four main reservoirs -- Poondi, Red Hills, Cholavaram and Chembarambakkam are dry.
In many areas, piped water is being supplied only once in three days. The authorities have deployed 300 water tankers in the city.
The Veeranam lake in Neyveli, a town more than 200 km away, from where Chennai receives supply through a huge pipeline is dry too. The authorities, however, are tapping other resources in the area to pump 90 million litres a day to Chennai through the same pipeline.
"Water is also coming in from stone quarries in Kancheeputam and Thiruvallur, besides two desalination plants in the city," a senior water supply official said.
The groundwater in Chennai and its surrounding areas is replenished by five lakes -- Puzhal, Sholavaram, Kaliveli, Pulicat and Maduranthakam -- all located within a 60-km radius of the city. In 2015, the lakes had overflowed due to unseasonal rains, causing devastating floods in Chennai.
Besides, there are thousands of water bodies in Chennai and its neighbouring districts. Green activists say had these water bodies been properly maintained, Chennai would never have suffered from water crisis. They blame rapid urbanization for the lack of upkeep of these water bodies.
